A Young double slit experimental setup is immersed in water of refractive index It has slit separation and the distance between slits and screen is . If the wavelength of incident light on slits is then the fringe width on screen is
- A
- B
- C
- D
Answer & Solution
Correct Answer
(B)
Step-by-step Solution
Detailed explanation
The fringe width when Young's double slit experiment setup is immersed in water, y=λDμd Substitute the given values in the above equation. y=6300×10-10×1.331.33×10-3 y=6.3×10-4 m y=0.63 mm
